In 2002, Princess Eugenie was treated for scoliosis, a condition that causes curvature of the spine

After being diagnosed with the condition at age 12, Eugenie said, she underwent an eight-hour surgery during which "surgeons inserted 8-inch titanium rods" into each side of her spine and "one-and-a-half-inch screws" at the top of her neck.

The princess said she intentionally chose a low-back wedding dress to honor her surgery and challenge conventional beauty standards

While speaking to ITV's "This Morning" before her big day, the princess hinted at her plan to honor both her surgery and the doctors who looked after her.

"I had an operation when I was 12 on my back, and you'll see on Friday, but it's a lovely way to honor the people who looked after me and a way of standing up for young people who also go through this," Eugenie told ITV's morning show host Eamonn Holmes.

By showing her scar during her wedding, the princess also hoped to challenge conventional beauty standards.

"I think you can change the way beauty is, and you can show people your scars and I think it's really special to stand up for that," she said.

People on Twitter said they loved Princess Eugenie's choice to show off her scar

While some Twitter users said that they loved Princess Eugenie's "body confidence," others said that the princess' choice to show her scar helped them find beauty in their own.
